In the manufacture of electrical apparatus such as is used, for example,in the telephone and radio art, a fiat'type of terminal l5, asillustrated in Figs. 7 and 14, is frequently used and in order to makean electrical connection therewith, a. connector wire [6 is wound inspiral fashion tightly around the terminal for several convolutions, andthe junction is enclosed. in solder to provide an. effective andprotected electrical connection.

' The winding of'the c'onnectorwire [6 about the terminal I5, whichheretofore has mainly been a manual operation, may be greatlyfacilitated by the use of portable wire winding devices of the typeherein disclosed.

Referring now to the embodiment of the invention disclosed in Figs. 1 to6, the device is disclosed as a pistol type of winding tool comprising ahousing 22 having a hand grip 24 extending downwardly therefrom. Securedin an aperture 26 (Fig. in a stationary boss 28 within the housing 22,as by means of a set screw 30, is one end of a stationary rod or shaft32. The rod 32 extends outwardly through an aperture in the housing andis provided at its forward end with a rectangular recess 36 forreceiving the end of the terminal I5 therein. A sleeve member 38rotatably mounted on the stationary rod 32 is secured by means of a setscrew 40 at its rear end in telescoping relation to a bushing M, which,in turn, is mounted for rotation on the rod 32 and within a bearingmember 42 secured to the housing 22.

At its rear end, the bushing 40 means of a pin 44 to a bevel gear 46,which is freely rotatable on the rod 32 and meshes with a bevel gear 48having a cylindrical hub 50, which is rotatably mounted in a bearingaperture in the bearing member 42. A pinion gear 52, secured to thebevel gear 49 for rotation therewith, meshes with a gear sector 53mounted for movement about a pivot pin 54 and having an operating ortrigger lever 56 extending therefrom through an aperture in the housing22. The sector 53 is stressed for rotation in a clockwise directionabout its pivot 54, as viewed in Fig. 1, by a spring 51, the rotarymovement of the sector in this direction being limited by a stop pin 58engageable with the arm 56. It will be apparent, from the descriptionthus far, that, upon engagement and actuation of the lever 56 in acounter-clockwise direction, the sleeve 38 will be caused to rotatethrough a predetermined number of revolutions, and, upon disengagementof the lever 56, the spring 51 will serve to rotate the sleeve 38 in theopposite direction and restore it to its normal position, as indicatedin Figs. 5 and 6 of the drawings.

At its forward end the sleeve 38 is provided with a longitudinal andradially extending slot for receiving a winding finger 62. The windingfinger 52 is pivotally mounted intermediate its ends on a pin 64 and hasits forward end 65 positioned slightly beyond the end of the rod 32. Aspring 66 engaging the rearwardly extending portion of the windingfinger 62 stresses the finger for rotation about the pin 64 to urge theforward end 65 into engagement with the end of the rod 32. Extendinglongitudinally of the winding finger 62 from the forward end 65 thereofis a recess or aperture 68 for receiving the connector wire 16 therein.The bore 66 is formed in the winding finger as by drilling while theforward portion of the winding finger is straight, and after the bore 68has been formed, the forward end 65 may be bent radially inwardly asshown in the drawings.

To enable the end 65 of the winding finger 62 to move into closeproximity to a terminal member I5 positioned in the recess 35 of the rod32, portions of the forward end of the rod 32 are cut away forming pairsof oppositely disposed inclined surfaces '|0-10 and I2-'|2 arranged inrectangular formation about the rectangular recess 36. The inclinedsurfaces 19-10 and 12--12, in addition to providing clearance for issecured by the movement radially inwardly of the end 65 of the windingfinger 62, form a cam track to guide the forward end 65 radially in andout, as the sleeve 38 and the winding finger 62 are rotated, to follow arectangular path correspondmg generally to the rectangular cross-sectionof the terminal I5.

' In using this device the operator while holdmg the device in one handinserts with the other hand the bared end of the connector wire I6 intothe aperture 68 of the winding finger 62 as indicated in Fig. l and thenmoves the winding tool or device relative to the terminal to cause theend of the terminal to be positioned within the recess 36 of thestationary rod 32. The conductor wire I6 may then be bent downwardly, asindicated in Fig. 6, and held there while the operator engages and movesthe lever 56 to actuate the driving mechanism and rotate the sleeve 38and the Winding finger 62 through a predetermined number of revolutions,approximately three and one-half. As the winding finger 62 is revolvedabout the rod 32, the forward end 65 thereof will guide the bared end ofthe connector wire I6 about the terminal and, as successive convolutionsare laid or wound on the terminal l5, they act to push the precedingconvolutions longitudinally thereon so that, on completion of thewinding operation, the end of the connector wire I6 will be Wound in aspiral form in tight engagement with the terminal and with theconvolutions thereof in tight engagement with each other as shown inFig. 7.

In the embodiment of the invention illustrated in Figs. 8 to 13, theWire winding device is shown as being of the manually operated pistoltype tool comprising a housing having a han-- die or pistol grip 9|. Arod or shaft 84, secured in a recess in a member 86 (Fig. 12) formed asa part of the housing 80, extends outwardly from the housing and, at itsforward end, is provided with a recess 88 for receiving one end of theterminal member I5, as illustrated in Figs. 10-13. A barrel or sleeve 90is rotatably mounted on the shaft 84 and is provided, at one end, withan enlarged aperture for telescopingly receiving therein a bushing 9|.Pins 92-92, fitting in apertures 93, and longitudinally extending slots94 in the bushing 9| and the sleeve 90, respec-- tively, operativelyconnect the sleeve 90 for rotary movement with and for axial movementrelative to the bushing 9|. The bushing 9| has fixed thereto, as bybeing pressed therein, a bevel gear 95, which meshes with a bevel gear96 mounted for rotation in a bearing member 98. Fixed to the bevel gear96 for rotation therewith 1s a gear I00, which meshes with a gear sectorIOI mounted for oscillating movement about a pivot pin I02. The sectorIOI has an operating arm I04 extending outwardly from the housing 80 andis stressed for rotation in a clockwise di rection, as viewed in Fig. 8,by a torsion spring I06, and a stop pin I01 serves to limit the rotationof the gear sector in this direction.

Screw threads Ill! formed in the shaft 84 are engaged by the threadedend of a plug I I I (Fig. 12) secured to the sleeve 99 by a threadedmember I I2 and serves to form a threaded connection between therotatable sleeve 90 and the non-rotatable shaft 34. Upon actuation ofthe operatmg arm I64, the drive is actuated to impart movement to thesleeve 99, causing it simultaneously to rotate through a predeterminednumber of revolutions and to move rearwardly on the shaft in a helicalpath. Upon release of the operating arm its, the torsion spr n I 6 a s,throu h the drive, to restore the sleeve to its normal position. A coilspring II l, interposed between the end of the bushing 9i and shoulderin the sleeve 90, serves to urge the sleeve longitudinally away from thebushing 52 and maintain the sleeve in its normal position, as indicatedin Figs. 12 and 13.

At its forward end, the sleeve 98 is provided with a radially andlongitudinally extending slot for receiving a winding finger I I8therein for r0- tation with the sleeve 98 and for pivotal movement abouta pin no carried by the sleeve. A head I 26, formed on the forward endof the winding finger I I8, is positioned. axially beyond the end of thestationary shaft 8d and extends radially inwardly toward the axis of theshaft as into close relation with a terminal positioned in the recess 38of the stationary shaft. A transversely extending groove I 22 is formedin the head IZQ for receiving the bared end of the connectar wire I6therein and for guiding the connector wire I about the terminal I5. Aspring iZd, engaging the rearwardly extending portion of the windingfinger I It, stresses the winding finger for rotation in acounter-clockwise direction about the pivot pin lit to urge the head I29thereof into engagement with the terminal member I5.

In order to align the connector wire It with the groove I22 in thewinding finger IE8 and to support it during rotation of the windingfinger, a stationary support and guide member I25 is positioned at theforward end of the shaft 84 and the sleeve 9 The guide member I25 isformed on the forward end of the bracket I25 secured to a portion of thehousing member 89, as illustrated in Figs. 8 and 9. The guide member I25has an axially disposed central aperture to provide clearance forrotation and radial outward movement of the head of the winding finger II8. In the upper wall of the member i25, a longitudinally extending slotIE8 is formed having an end wall engageable with the end of theconnector wire It to locate the wir It in a predetermined positionrelative to the head I26 of the winding finger I It and to a terminal I5positioned in the recess 85. In the lower right-hand portion of theguide I25, as viewed from the front (Fig. 11) a relatively wide recessI29 is formed to provide clearance for the reception of the free end ofthe i connector wire I5. When located in the end of the slot I28, asindicated in 10 and 11, the connector wire It is positioned adjacent theteriinal E 5 about which the connector wire is to be wound in alignmentwith the groove I22 in i the head I26 of the winding finger H8.

The other end of the winding finger IIB is inclined to form a camsurface I 32, which coopcrates with an annular conical cam surface I3 lformed on a sleeve 35 mounted for reciprocable movement on the sleeve5i). A ring I secured to the inner portion of the barrel I35 forms ashoulder for receiving the thrust of a coiled sprin I33 which reactsagainst the shoulder I39 on the sleeve 99 and serves to urge the sleeveI35 rearwardiy to its normal position where it engages a portion of thehousing 38, as shown in Fig. 13. A lever use, pivoted at its upper end I32 to the sleeve E35 and fulcrumed intermediate its ends at I53 to thebracket 5%, has a finger piece I4 3; by means of which the lever may beactuated to impart forward axial movement to the sleeve I35 and causethe rocking of the winding finger H8 to a position permitting theapplication or insertion of the connector wire H6.

. nal in the recess 88 of the non-rotatable shaft 84 as illustrated inFigs. 12 and 13. With the index finger, the operator may then rock theactuat-' ing lever I68 to advance the sleeve I35 and rock the windingfinger H8 to its open or inoperative position, with the head I20 thereofspaced from the terminal I5, after which the hatred end of the connectorwire I6 may be placed in front of the guide I20, aligned with the slotI28 therein and moved axially into engagement with the end thereof,after which the actuatin lever I40 may be released to permit theretraction of the sleeve I35 and the movement of the winding finger I I8to its normal position. As the head I23 of the winding finger I I8 movesradially inwardly, it engages the connector wire IS in the groove I22thereof and urges it into firm engagement with the terminal I5. Theupper portion of the conhector Wire I6 may be bent transversely andmanually held in a fixed position on the supporting guide member I25, asindicated in Figs. 10 and 11. The operator may then engage and actuatethe lever Illi which through the gear drive imparts rotation to thesleeve 953 through approximately three and one-half revolutions andsimultaneously therewith causes an axial movement rearwardly of thesleeve relative to the stationary shaft and the terminal I5. During thisrotary and axial movement of the sleeve, the winding finger IIS movingtherewith serves to wrap the iree end of the connector wire I6 spirallyand tightly about the terminal I5 and with the convolutions thereof inspaced relation to each other as indicated in Fig. 14. Since thedownwardly extending free end of the connector wire It, a portion ofwhich is shown in Fig. 11, is longer than the radius of the centralaxial aperture through the guide member I26, the connector wire it isbent into a loop by the head I253 of the winding finger H8 as thewinding finger II8 rotates to wind the Wire IE about the terminal I5,and the free end of the loop gets progressively shorter as the wire I5passes through the groove I22 as it is progressively wound onto theterminal. On completion of the winding operation, the winding device maybe withdrawn axially from the terminal IE and the connection formedthereon by the connector wire I6.

It is to be understood that the above-described arrangements are simplyillustrative of the application of the principles of the invention.Numerous other arrangements may be readily devised by those skilled inthe art which will embody the principles of the invention and fallwithinthe spirit and scope thereof.
